Deep sea equipment is not afraid of pressure! Ultra-high pressure testing machine to escort
In recent years, with the continuous deepening of deep-sea exploration and resource development, the pressure resistance performance of deep-sea equipment has become a key challenge. The emergence of ultra-high-pressure testing machines provides an important guarantee for the safety and reliability of deep-sea equipment. This article will combine the hot topics and hot content on the Internet in the past 10 days to analyze the latest progress of deep-sea equipment pressure resistance technology.
1. The importance of pressure-resistant technology for deep-sea equipment
The pressure in the deep sea environment is huge. Every time you dive 10 meters, the pressure increases by about 1 atmosphere. In the Mariana Trench, which is 10,000 meters deep, the pressure can reach more than 1,000 atmospheres. Therefore, deep-sea equipment must have extremely strong pressure resistance, otherwise it may be damaged due to excessive pressure, or even cause serious accidents.
| Deep sea depth (meters) | Pressure (atmospheric pressure) | Typical equipment |
|---|---|---|
| 1000 | 100 | submersibles, sensors |
| 6000 | 600 | deep sea detector |
| 11000 | 1100 | Full sea deep manned submersible |
2. Core technology of ultra-high pressure testing machine
The ultra-high pressure testing machine is a key equipment for simulating the deep sea high-pressure environment. Its core technologies include high-pressure sealing, pressure control and material strength testing. The following are the technical highlights of ultra-high voltage testing machines that have been hotly discussed on the Internet in the past 10 days:
| Technical name | Function | Application scenarios |
|---|---|---|
| Multi-layer composite seal | Prevent high pressure leakage | Deep sea equipment cabin testing |
| Intelligent pressure control | Accurately simulate pressure changes | Equipment ultimate pressure test |
| Non-destructive testing technology | Monitor equipment status in real time | Material fatigue analysis |
3. Recent hot events in deep sea technology
1.China's "Struggle" sets another record: Recently, my country's "Struggle" full-sea deep manned submersible successfully completed 21 dives of 10,000 meters, and its pressure resistance passed the rigorous test of an ultra-high pressure testing machine.
2.New breakthrough in deep sea energy development: A certain country announced the discovery of a large oil and gas field at a depth of 3,000 meters, and the pressure-resistant technology of deep-sea drilling equipment became the focus of attention.
3.International Deep Sea Equipment Exhibition: At the International Deep Sea Equipment Exhibition held last week, a number of new ultra-high pressure testing machines were unveiled, which can simulate the 12,000-meter deep sea pressure environment.
4. Comparison of pressure resistance standards for deep sea equipment
Different countries have different pressure-resistant standards for deep-sea equipment. The following is a comparison of the standards of major countries:
| nation | Standard name | Test pressure | Applicable depth |
|---|---|---|---|
| China | GB/T 34520 | 1200 atmosphere | 11,000 meters |
| USA | API 17F | 1000 atmospheres | 10000 meters |
| Japan | JIS F0401 | 800 atmospheres | 8000 meters |
5. Future development trends
1.Higher stress testing requirements: As humans explore deeper seas, the demand for testing 15,000-meter-level equipment will grow day by day.
2.Intelligent testing system: Intelligent stress testing systems combined with AI technology will become the focus of research and development, enabling automated testing and data analysis.
3.New material applications: The pressure resistance performance test of new materials such as graphene will provide new ideas for lightweighting deep-sea equipment.
Deep-sea exploration is the last frontier of human understanding of the earth, and ultra-high-pressure testing machines are an important guarantee for ensuring the safety and reliability of deep-sea equipment. With the continuous advancement of technology, we will surely uncover more mysteries of the deep sea and contribute to the sustainable development of mankind.
